CHARLES S. KLINE, OF MINGrO JUNCTION, OHIO.

WRENCH.

SPECIFICATION forming part of Letters Patent N0. 752,564, dated February 16, 1904. I

Application filed October 10, 1903.

To all whom it may concern.-

Be it known that I, CHARLES S. KLINE, a citizen of the United States, residing at Mingo Junction, in the county of J eiferson and State of Ohio, have invented new and useful Improvements in Wrenches, of which the following is a specification.

My invention relates to new and useful improvements in wrenches especially adapted for use in removing drills subsequent to a drilling operation.

It is well known that when drills are used extreme difiiculty is experienced in removing them in view of the fact that such removal is resisted by the vacuum created when the outward pull is exerted thereupon. Furthermore, the drill is oftentimes covered with mud, and a firm grip thereon by an ordinary wrench is thus difficult to obtain.

The object of my invention is to provide a light, simple, and inexpensive device of novel construction which can be readily attached to a drill and will when drawn upward by means of its handle firmly grasp the drill and draw the same outward.

The invention consists in providing a bar having a handle at oneend and a yoke at the other end, said yoke having a concave working face provided with teeth for gripping thetool to be engaged. Ahooked arm is pivotally connected to the bar and extends downdard and under the yoke, said hook being so shaped as to extend around and firmly grasp the drill.

The invention also consists in the novel construction and arrangement of the several parts, which will be more fully hereinafter described and claimed.

In the drawings, Figure 1 is a perspective view of the device. Fig. 2 is a side elevation thereof in positionupon a drill.

Referring to the figures by numerals of reference, l is a bar having ahandle 2 at one end, while the other end is provided with a yoke 3, the working face of which is concave and provided with teeth 4. Pivotally connected to the bar is a yoke 5, from which ex- Serial No. 176,509. (No model.)

tends an L-shaped arm 6, having a laterallyextending hook 7 at its free end. The hook is located, preferably, in alinement with the end of the yoke 3, and in using the tool the hook 7 is placed in engagement with a drill 8, and the toothed face of the yoke 3 is then pressed against the opposite wall of said drill. When upward pressure is exerted upon the handle 2, the drill will be firmly gripped by the hook and the yoke, and the possibility of the tool slipping upon thedrill is prevented by the teeth 4. It will be understood that the greater the pressure exerted upon the handle the firmer will be the grip of the tool upon the drill. I

While the tool is especially adapted for the purpose above described, it will be understood that it can be also used for gripping and turning pipes, rods, and other similar articles.

In the foregoing description I have shown the preferred form of my invention; but I do not limit myself thereto, as I am aware that modifications may be made therein without departing from the spirit of the invention, and I therefore reserve the right to make such changes as fairly fall within the scope thereof.

Having thus fully described the invention,

what is claimed as new is 1. The combination with a bar having a handle at one end and a toothed yoke at the other end; of a hooked arm pivoted to the bar and adapted to engage the opposite side of an object within the yoke.

2. The combination with a bar having a handle at one end and a toothed yoke at the other end; of an L-shaped armpivotally-connected at one end to the bar and having a lat-
